PROBLEM TO BE SOLVED: To provide a planar heating element capable of preventing fogging due to rain, freezing, and the like, removing the fogging when the fogging is generated, and securing stable field vision.SOLUTION: There is disclosed a planar heating element 10 which includes: a resin-made substrate; heat rays 12a, 12b which are an aggregation of a basic cell 12 formed on the substrate; a connection line 13 which connects basic cells to each other; and a power feeding line 14 connected to the heat ray. The basic cell constituting the heat ray is constituted by the line, formed in a closed shape, and has a contact point 12c connected to the connection line or an electric wire at two places of positions opposite to each other with respect to the graphic center of the basic cell. In the aggregation of the basic cell, series of basic cells are connected to each other via the connection line connected to the contact point, and both terminals are composed of a connection group of basic cells connected to the power feeding line or composed of the connection group of aggregation of a plurality of basic cells.SELECTED DRAWING: Figure 1

    【課題】雨や凍結等に起因する曇りを防止することができるとともに、曇りが発生した場合には、曇りを除去することが可能であるとともに、安定した視界の確保が可能な面状発熱体を提供する。【解決手段】樹脂製の基体と、基体上に形成された基本セル12の集合体である熱線12a,12bと、基本セル同士を接続する接続線13と、熱線と接続された給電線14とを備えた面状発熱体10であって、熱線を構成する基本セルは、線により構成され、閉じた形状をなし、基本セルの図形中心に対して互いに対向する位置となる2カ所に接続線又は給電線と接続される接点12cを有し、基本セルの集合体は、一連の基本セルが接点に接続された接続線を介して相互に接続され、その両末端が給電線と接続された基本セル接続グループからなるか、又は、基本セル接続グループが複数個集合したものであることを特徴とする面状発熱体。【選択図】図1
